The dracaena plant is a popular ornamental houseplant, grown both indoors and outdoors in subtropical climates. It reaches a height of about 3' indoors, and has a bushy tree type of look. Its glossy leaves can grow up to one foot long and a couple of inches wide. Not only does its dramatic foliage with beautiful colour patterns make a great focal point in any room, but dracaena can also help improve air quality. Wiping both the upper surfaces and undersides of the leaves regularly with a damp cloth allows the plant to exchange air freely.
